Title: Semiconductor device
Inventor: NAGAI YUTAKA
IPC: H01L21/314
Filed: 1987-11-25
Abstract: PURPOSE:To prevent a stress, a defect, and a transition from penetrating into a crystal by a method wherein a distorted superlattice layer composed of two or more kinds of thin layers whose lattice constants are different from each other is formed on a surface of a semiconductor crystal which is in contact with a film formed of a material whose thermal expansion coefficient is different from that of the semiconductor crystal. CONSTITUTION:A distorted superlattice layer 6 is formed in such a manner that two or more kinds of layers whose lattice constants are different from each other are alternately laminated, and each layer of distorted superlattice layers 6a and 6b shrinks and expands mutually due to the inner stress, so that a lattice misalignment is absorbed. When an insulating film 7 whose thermal expansion coefficient is different from that of the distorted superlattice layer 6 is formed contacting the layer 6, the thermal constant difference between them makes an inner stress act on a crystal, where the inner stress in the superlattice layer 6 changes to alleviate the inner stress applied by the insulating film 7. In result, the inner stress applied by the insulating film 7 is prevented from being conveyed inside the crystal. And, the distorted superlattice layer 6 has a property that prevents penetration of the transition.
